But now it's going to make more sense because in that case we were just talking about single electron atoms, and now we're talking about a case where we actually can see shielding.
但是现在能讲得通了,因为在那个情况中我们仅仅是现在我们讨论的是,讨论单电子原子,看到屏蔽的案例,我们能看到屏蔽。
So what we'll have here is a trigonal planar case, and you can see that we only have three electrons that are set for bonding, so we'll add three hydrogens, and for b h 3, we'll get a stable structure here.
让电子劲量远离的时候,不用考虑它,这个例子是平面三角形,你可以看到,只有3个电子可以成键。
We're going to see an example of that in a second. What we really want to worry about, what's the worst case that happens.
我们接下来就来看一个这样的例子,我们要关注的是,发生的最坏情况是什么呢?
